A person travels by car from one city to another with different constant speeds between pairs of cities. She drives for 25.0 min at 95.0 km/h, 14.0 min at 70.0 km/h, and 40.0 min at 40.0 km/h and spends 60.0 min eating lunch and buying gas.

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
